在Python中将csv文件转换为管道分隔文件

我想使用 Python 将逗号分隔的 CSV 文件转换为管道分隔的文件：

这就是我读取 csv 文件的方式：

with open('C://Path//InputFile.csv') as fOpen:
    reader     =     csv.DictReader(fOpen)

    for row in reader:
        for (k, v) in row.items():
            columns[k].append(v)

c = csv.writer(open("C://Path//OutputFile.txt","wb"), delimiter="|")

我如何将其写为管道分隔文件？

import csv

with open('C:/Path/InputFile.csv') as fin:
    # newline='' prevents extra newlines when using Python 3 on Windows

    with open('C:/Path/OutputFile.txt', 'w', newline='') as fout:
        reader = csv.DictReader(fin, delimiter=',')
        writer = csv.DictWriter(fout, reader.fieldnames, delimiter='|')
        writer.writeheader()
        writer.writerows(reader)
